IMPROVEMENT IN WINDLASS WATER-ELEVATORS.

Specification forming part of Lettels Patent No. l48,266, dated March 3, 1874; application filed v December 24, 1873.

To all whom it may concern:

Be it known that I, NATHAN B. VOSBURGH, of Livingston county, Missouri, have invented certain new and useful Improvements in I/Vindlass later-Elevators, of which the following is a specification, reference being had to the accompanying drawings.

The invention relates to windlass waterelevators 5 and consists of two rollers loosely secured upon a shaft, and provided on their inner ends with beveled gear-wheels, which engage a beveled pinion operated by a horizontal lever, the end of which is clasped about au annular slot in a clutch, which slides upon and turns with the shaft, and, by the operation of the lever, engages either one of the ratehets at the center ofthe gear-wheels. Attached to each roller is a chain or rope, provided with a bucket having ears upon its rim midway between the handle, Yso that as the bucket is elevated, the ear engages a hinged curb, thus tilting the bucket and emptying its contents. The object of the invention is to provide a continuous means of elevating` water.

Figure 1 is a top or plan view of a device embodying the elements of the invention. Fig. 2 is a vertical central longitudinal section through the central part-sof the elevating' mechanism. Fig. 3 is a vertical section through the clasp, clutch, and operating-shaft.

A in the accompanying drawings is the framing of a well-curb, which is placed about the mouth ofthe well. B are posts or uprights, sustaining the bars c b. Upon the latter is secured, in journals, at a proper place, the ends ofthe shaft D, which is operated by a crank, a. To the shaft D are loosely secured the rollers E, separated a proper distance between their inner ends, whereon are placed the beveled gear-wheels F, the teeth of which engage the beveled pinion H, rotating between the chocks 7i upon the lever I, one end of which extends over the front of the frame A, passing through the support L, and having a proper lateral play. The pinion H is movable upon the lever I, and may be xed in any desired position by the movable chocks 7L, which are secured upon the lever by set-screws. The other end of the lever is formed into a clasp or clamp, t, which fits loosely in an annular slot, m, passing around the vertical center of the clutch M, which is arranged to slide laterally upon the shaft D, which is here provided with a key-guide, t', fitting into a slot, z, in the axis of the clutch M, which may thus be moved upon and rotate with the shaft D without hinderance from the lever I, by which it can be moved so as to engage the ratcli'ets N,

placed about the centers of the wheels F.

Ghocks l are provided upon the shaft D at the outer ends of the rollers to keep them in proper position. To the center of each of the rollers is secured one end of the chains 0r ropes n, y

which are of like length, and have their other ends secured to the buckets l?, near the rim of which, and midway between the handles, are provided the tilting-ears It, placed opposite each other, and projecting upward and outward. A hinged curb, T, is placed below and in front of the rollers, in such position that as a bucket is elevated the ear R shall come in contact with it, thereby tipping the bucket, and emptying its contents into the trough U in the front of the frame A, whence the liquid passes through the spout V.

The operation is as follows: The clutch M being thrown into contact with one Aof the ratchets N, the crank c is rotated, causing the clutch to act upon the ratchet, thus revolving one of the gear-wheels F,'which engages the pinion H, communicating a contrarevolution to the other wheel F. Thus the rollers E are rotated in opposite directions, one rope being taken up and the other let out, respectively, elevating and lowering the buckets P. This operation is continued until the ear R on the ascending bucket, coming in contact with the curb T, causes the bucket to empty its contents into the trough U. The lever I is now shifted, throwing the clutch M into contact with the opposite ratchet N, thus reversing the movement of the rollers E and elevating the descended bucket without checking the rotation of the shaft D.

I do not claim, broadly, operating a sliding clutch by means of a pin Working in an annular groove, or a fork Working upon an annular shoulder of a sliding clutch; but

That I do claim as my invention, and desire to secure by Letters Patent, is-

The lever I, passing through and sustaining,r the pinion H, and provided with the ehoeks h for the adjustment of the pinion, the rear end of the lever being' provided with the clasp k, placed in the slot m, and encompassing,1 the clutch M, so as to move it evenly, all substantally as shown and set forth.

In testimony that I claim the Yforegoing improvements in Windlass Water elevators, es above described, I have hereunto set my hand and seul this 8th day of December, 1873.
